Patent CA-2327338-C (CA)
Title: Automated and selective authentication in transaction-based networks
Inventor: BAULIER GERALD DONALD
IPC: H04M3/42
Filed: 1999-04-05
Granted: 2004-09-21
Abstract: Fraud losses in a communication network are substantially reduced by automatically and selectively invoking one or more authentication measures based on a fraud score that indicates the likelihood of fraud for that particular call or previously scored calls. By selectively invoking authentication on only those calls that are suspected or confirmed to be fraudulent, fraud prevention can be achieved in a way that both reduced fraud losses and minimizes disruptions to legitimate subscribers. Using telecommunication fraud as an example, a subscriber is registered in a system by collecting data on that subscriber based on the particular authentication method being used, such as shared knowledge (e.g., passwords), bio-metric validation (e.g., voice verification), and the like. Once registered, the authentication function for the subscriber's account is activated and subsequent calls are then scored for the likelihood of fraud during the call setup request phase. Fraud scoring estimates the probability of fraud for each call based on the learned behavior of an individual subscriber and the learned behavior of fraud perpetrators. If fraud is not suspected based on the fraud score, then normal call processing can resume without the need for authentication. if fraud is suspected based on the fraud score, then the system automatically invokes authentication. If authentication indicates suspicion of fraud, e.g., voice prints do not match, then the call may either be blocked or referred for other appropriate prevention measures, e.g., intercepted by an operator. If fraud is not indicated by authentication, then normal call processing may resume.

Granted: 2008-01-08
Abstract: The invention concerns the control of connections in cellular telecommunication systems According to the invention, the available radio resources are controlled by allowing only certain combinations of transport formats to be used by a single user. The inventive method restricts the combinations of bearer bit rates which can be used, without strictly limiting some bearers from using the highest bit rate. This inventive approach allows flexible overall control of radio resources, while retaining the possibility of bearers to select between different bit rates.

Title: Method for producing polyhydroxyalkanoates in recombinant organisms
Inventor: AQUIN STEPHANIE
IPC: C12N15/52
Filed: 2000-03-15
Granted: 2009-08-25
Abstract: The present biotechnological approach for the production of polyhydroxyalkanoates (PHAs) uses microbial systems. The high production costs make them substantially more expensive than synthetic plastics. Engineering a novel pathway in eucaryotic cell systems is a beneficial alternative to the production of PHAs in bacteria. This pathway will initially produce free (C8) fatty acids from the fatty acid synthetic pathway through the action of thioesterase, that will then add a CoA moiety to the free fatty acid through the action of an acyl-CoA synthetase, that will produce 3-ketoacyl-CoAs from the acyl-CoA through the action of a thiolase, that will produce R-(-)-OH-acyl-CoAs from the 3-keto acid CoAs through the action of a dehydrogenase isoform from yeasts. These R-(-)-3-OH-acyl-CoAs will finally be used as substrate for the PHA synthase reaction.
